scope:

The supplemental tables presented in this document are intended for use with the evaluation procedures presented in CLSI document EP07-Interference Testing in Clinical Chemistry. EP07 describes protocols for manufacturers of in vitro diagnostic measurement procedures to screen potentially interfering substances, quantify interference effects, and confirm interference in patient samples. It also describes procedures for medical laboratories to verify interference claims and investigate discrepant results caused by unsuspected interfering substances. The supplemental tables in EP37 provide recommended test concentrations for analytes and endogenous substances that may interfere in clinical chemistry measurement procedures.
